Discuss power management solutions. Ask questions and find answers on voltage configurations, short circuit protection, and programming.
Per example code of L9369, to set SPI_set_PWM, one read-write operation for 6Ah is used and to set SPI_PWM_A, another read-write operation for 6Ah is used. My question: Can two separate read-write operations be merged into only one？ Thanks!
EN_EL pin (#47) is originally EN function and to set it as RST function， need to set D[4] of reg8Ah. My question: When to set D[4] to 1 to enable RST function? should it do after setting watchdog ? Thanks! RST Remapping on EN_EL the function of I...
Hi.I am using the L6599AD without PFC.Previously, the DIS pin was connected to the DELAY pin and used as a SHUTDOWN.However, the frequent peak current caused SHUTDOWN.So I connected the DIS pin to GROUND and made it work in HICCUP MODE.However, the ...
Hello,I have developed a custom board using the STPM33 to measure power consumption. The schematic is identical to the evaluation board.I can communicate with the STPM33 via SPI and have verified that the data I write is correctly stored in the devic...
Hello Anyone did ever you use the MC34063ACD-TR for to power on a "MCU" at 3.3V? From datasheet it seems it needs change R1 and R2 for to obtain the goal but the figure 15 shows until 5V so..I ask you if i can use it for my application. My applicatio...
我的WLC99RX开发板无法连接到GUI，我下载了wlc_ft260_Recovery这个文件，我连接了STEVALUSBI2C，但是并没有用，可不可以给我一个详细的教程。我还有一个问题是解释我的GUI界面似乎与开发板手册上的展示的不一样，GITHUB网页已经404，请问可以通过邮箱发给我与手册上展示一样的GUI软件吗，谢谢 Translation: My WLC99RX development board cannot connect to the GUI. I downloaded the ...

HiI have a motor contol design for a 4pole motor 4800 rpm but my control seem to be limiting the speed to 300-500rpmI have followed the app note AN1625 and using a integrator circuit. I can adjust vspeed voltage via a pot. but this does not change th...
Hi Team,We have designed our own SMPS with a charger board, which converts 230V AC to 24V DC. In this design, we used an LM2596 buck converter circuit to limit the voltage to 24V when the battery is fully charged (29.4V). However, the output voltage ...
Hello,I'm developing a charging solution using the STWBC86 controller - is it possible to disable the reping after a received EPT packet from the receiver device (GUI setting: TX EPT PING DIS EX EPT) only while it detects the presence of a receiving ...
